Embodiment 1:
A kind of paving structure of orthotropic plate rigidity enhancing, as shown in Figure 1, including orthotropic plate 1, in orthotropic
Longitudinal rib 12 and cross rib 13 are equipped on the downside of steel plate 1, longitudinal rib 12 and cross rib 13 are mutually perpendicular to.Preferably, longitudinal rib 12 is that interval is set
The U-shaped rib 121 and/or board-like rib 122 set.
As shown in Figure 1, nanometer antiwear layer 11, micro- buffer layer 2 and wearing course 3 are successively arranged on the upside of orthotropic plate 1, it is resistance to
Grind nanometer layer 11 and the upside of orthotropic plate 1 penetrated by micro- plasma infiltration method, nanometer antiwear layer 11 be FeB chemical compound or
Person's manganese boron compound, both compounds significantly improve the hardness on 1 surface of orthotropic plate and wearability, are not easy it
Fatigue cracking or overload breakage occur under the action of long-time service or heavy load.
As shown in Figure 1, micro- buffer layer 2 passes through side bonds on resin and nanometer antiwear layer 11, pass through tree on the upside of micro- buffer layer 2
Rouge is bonded with sheet metal 4, and sheet metal 4 buffers orthotropic plate 1, reduces outer bound pair orthotropic plate 1 as far as possible
Active force.On the upside of sheet metal 4 by micro- plasma method penetrate into nano porous layer 41, nano porous layer 41 be FeB chemical compound or
Person's manganese boron compound, wearing course 3 are made of pitch and concrete, and are cast in nano porous layer 41.Due to nano porous layer
41 is different from the formula of nanometer antiwear layer 11, therefore the performance of final infiltration layer obtained is different, and nanometer antiwear layer 11 mainly mentions
The high hardness and wearability on 1 surface of orthotropic plate, and after nano porous layer 41 penetrates into sheet metal 4,4 surface of sheet metal
Hardness and wearability can also increase, but the surface roughness of sheet metal 4 is greater than the rough surface of orthotropic plate 1
Degree, therefore sheet metal 4, when being combined with wearing course 3, bond strength is higher.
As shown in Figure 1, micro- about 2 two sides of buffer layer, which are all made of fiber cloth and resin solidification, forms scrim cloth 21, two layers
The bolster 22 of buffering Light deformation is equipped in scrim cloth 21.Preferably, the bolster 22 in the present embodiment is " people " word
Shape profile, bolster 22 are arranged perpendicular to micro- buffer layer 2, between adjacent buffer part 22 between formed U-shaped cavity 221, cavity
Filler 5 is filled in 221, filler 5 is hard polyurethane foam or rock wool.It is deposited between opposite both ends 22 lower part of adjacent buffer part
In gap 222 to adapt to the deformation that bolster 22 is generated with seasonal variations." people " font profile is on the one hand to entire orthotropic
The mechanism of mating formation of plate enhancing plays support invigoration effect, on the other hand, when by extraneous load, the arc section of 22 lower section of bolster
Micro- deformation can occur, reduce the stress of orthotropic plate 1, keep orthotropic plate 1 not easy to break, extend it and use the longevity
Life, to improve the crack resistance and stability of the mechanism of mating formation of orthotropic plate enhancing.
Embodiment 2:
A kind of paving structure of orthotropic plate rigidity enhancing, difference from example 1 is that, as shown in Fig. 2, buffering
Part 22 include several support sheets 223 being equipped with and wavy buffer substrate tablet 224, the both ends of support sheet 223 respectively with
Scrim cloth 21 is bonded, and the both ends of buffer substrate tablet 224 are vacantly arranged with scrim cloth 21 not in contact with support sheet 223 is along longitudinal direction
Several notches 2231 being embedded in for buffer substrate tablet 224 are offered, buffer substrate tablet 224 is embedded in part and the support sheet 223 of notch 2231
Bonding is filled with filler 5 in gap between bolster 22 and micro- buffer layer 2.Support sheet 223 is for being embedded buffer substrate tablet 224, separately
Outside, the mechanism of mating formation that can enhance entire orthotropic plate plays support invigoration effect.When by extraneous load, buffer substrate tablet
224 can be by vibration guidance to buffer substrate tablet 224, and buffer substrate tablet 224 transmits these vibrations to filler 5, and filler 5 has certain shape
Change ability, therefore, micro- buffer layer 2 can substantially reduce the stress of orthotropic plate 1, keep orthotropic plate 1 not easy to break,
It prolongs its service life, to improve the crack resistance and stability of the mechanism of mating formation of orthotropic plate enhancing.
